WINDOW- SCREEN.

SPECIFICATIGN forming part of Letters Patent No. 696,788, dated April 1,1902,

Application led July 6, 1901. Serial No. 67,342. (No model.)

T @ZZ whom, t may concern:

Be it known that I, HENRY T. vVRIGHT, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a certain new and useful Improvement inVVindow-Screens, of which the following is a specification.

My invention relates to a new and useful improvement in window-screens;and it has for its object to provide a window-screen which is detachablysecured to the lower rail of the lower sash and the upper rail of theupper sash, so that the screen can be raised i and lowered with thewindow, an opening being formed through the casing and a recess formedin the wall for the reception of the screen.

With these en ds in View this invention consistsin the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand howto make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which-Figure l is a front elevation of a window, showing my screen attachedthereto. Fig. 2 is a Vertical section of the lower part of a window,showing the lower sash partially raised and one of my screens attachedthereto; Fig. 3, a section on the line 3 3 of Fig. l; and Fig. a, afront elevation of the lower rail of the lower sash, a portion beingbroken away to show the mechanism which secures the screen to the sash.Fig. 5 is a perspective view of one corner of the screen, showing thetop flange cut away to allow for the sidewise motion of the screen inremoving the same.

dow-sash I provide in the lower cross-rail of the lower sash and theupper cross-rail of the upper sash a stud D, to which4 is adapted to besecured the spring-arms E. The natural tendency of these arms is tospring together, as shown in dotted lines in Fig. 4. Upon the free endsof the spring-arms are provided the beveled portions E', projectingoutward. A slot C2 is provided through the horizontal flange C of thescreen, and when the windowsash is brought against the iiange C the freeend of the spring-arms E will project through the slot C2, and if thearms E are then spread, so that said arms come in contact with the endsof the slot, the beveled projections E will hold the screen in contactwith the sash. For the purpose of spreading these arms I provide theturn-button G, which is secured to the'stud G', which projects outwardto the front of the sash and is there provided with a knob, so that thesame can be rotated. This turn-button G is oblong and has flattenedsurfaces on each of its four faces, the corners being rounded, and whenthis button is turned as shown in dotted lines in Fig. 4, with itsgreatest length in its vertical position, it will allow the ends of thespring-arms E to come together to allow for the insertion through theslot G2, and after they are inserted through the slot the button G isthen turned in the position shown in full lines in- Fig. 4, with itsgreatest length in its horizontal position, which will cause the arms Eto be spread and come in contact with the ends of the slot C2. Thebeveled surfaces upon the projections E will force the flange C intotight contact with the sash.

H is a recess or opening formed in the wall into which the screen isadapted to recede when the windows are closed, and when the screens aredetached from the windows said screens are adapted to be held in theserecesses, being entirely out of sight, but always ready for use whenrequired.

I represents slots formed through the upright side pieces of thewindow-casing, into which the side frames of the screen are adapted toslide and be guided as they are raised and lowered.

When it is desired to remove the screen entirely, the screen is raiseduntil it is entirely out of its recess Il, and then by detac'hing thesame from the Window-sash it can be pushed to one side Within the slot Iuntil the other side is free and can be removed in that way. The plate Cwill be cut away sufiiciently at the side to allow for this movement.

The advantage of my invention is that a screen will be provided whichcan be readily attached or detached, and the window can be raised orlowered any distance desired and still prevent the entrance of insectsto the room, and in winter or any other time when it is not desired touse the screen the same will be out of the way and out of sightentirely, but ready for instant use at any time.

Vhen the lower screen is detached from the sash, it will remain in itsrecess by-reason of gravity, its own weight being sufcient to hold it inposition. Vhen the upper screen is removed from the sash, it may eitherhave light Weights ruiming over pulleys attached to the same to hold itupward in position, or other means, such as turn-buttons or frictionalsprings, may be employed to hold it Within its recess.

Another advantage of my invention is that the life of the screen will beprolonged, because it is not necessary to handle the screen at all.

lA further advantage of my invention is that the knobs connected to thelatches, which secure the screen to the sash, are only upon the insideof the room, and therefore form a lock whereby no one could enter theroom while the window is raised without cutting the screen. Of coursethis would only be of use in preventing slight depredations, but wouldbe much safer than the ordinary screens now used, which can be raised orremoved frein the outside as well as the inside.

- Of course in brick or stone houses the window would have to beconstructed especially for my screen; but in frame houses it would onlybe necessary to make an opening through the sill of the window-casing,and the screen could then be passed between the outer and innersheathing of the wall.

Of course I do not Wish to be limited to the exact construction hereshown, as slight modiiications could be made without departing from thespirit ot my invention.

Having thus fully described my invention, what I claim as new and usefulisl. In an apparatus of the character described, a window-screen, ahorizontal flange formed With the upper portion et the frameeeegse workof said screen, said flange adapted to come in contact with the sash,means for detachably securing said flange to the sash for the purpose ofraising and lowering the screen with the sash, a recess formed in thewall in which the screen is adapted to recede when the sash is closed,guideways formed in the upright portion of the window-casing in whichthe side frames of the screen are adapted to slide, said guideways beingsuch as to allow the screen to be pushed a sufficient distance to oneside to allow the removal of' one edge of the screen for the purpose ofremoving the screen entirely, substantially as described and for thepurpose specified.

2. In combination with an apparatus of the character described, ascreen, a horizontal fiange formed with the upper framework of thescreen, a slot formed through said iiange, spring-arms arranged withinthe cross-rails of the sash, beveled projecting portions formed upon thefree end of the spring-arms, said spring-arms adapted to be normally incontact with one another for the purpose of inserting the same throughthe slot in the flange of the screen, means for spreading saidspring-arms for the purpose of attaching the screen to the sash,substantially as and for the purpose set forth.

3. In combination with an apparatus ofthe character described, twospring-arms secured in the cross-rail of the window-sash, the free endsof said spring-arms projecting beyond the sash, outwardly-extendingbeveled'portions formed upon the free end of said springarms, saidspring-arms adapted to be in contact with one another when in theirnormal position, a slot formed. within the screenframe through which theends ofthe springarms are adapted to protrude when the screen is broughtin contact with the sash, an oblong button adapted to be pivoted betweenthe springarms,said button adapted to spread the arms when turned to itsgreatest length in a horizontal position, a knob secured upon theoutside of the sash for the purpose of turning said button,substantially as and'for the purpose set forth.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses. y
